It is speculated that the "K" in KUFO stands for "Krap". The letter "K" is often used in place of a "C" to symbolize either a child at an entry level of reading, or an adult of sub-par intelligence.
It is also speculated by some that this term came from the radio station's crappy selection of music which people put up with only to hear their favorite radio personalities.
2. We're really getting hit by KUFO these days, what with all these reality shows on TV.
Wow, my Windows 98 PC sure is taking a KUFO right now.
